Various pulsar timing array (PTA) experiments (NANOGrav, EPTA, PPTA, CPTA, including
data from InPTA) very recently reported evidence for excess red common-spectrum signals …

In the context of scalar-tensor theories of gravity we compute the third-order corrected
spectral indices in the slow-roll approximation. The calculation is carried out by employing …

It has been previously shown that the linear inflation appears naturally as a solution of
Coleman-Weinberg inflation, provided that the inflaton has a non-minimal coupling to gravity …

We consider an inflationary kinetic function with an integrable pole that is traversed during
inflation. This scenario leads to enhanced spectra of primordial scalar inhomogeneities with …

We investigate inflationary dynamics in the framework of the Einstein-Gauss-Bonnet gravity.
In the model under consideration, the inflaton field is nonminimally coupled to the Gauss …

We study a scale-invariant model of quadratic gravity with a nonminimally coupled scalar
field. We focus on cosmological solutions and find that scale invariance is spontaneously …

In constant-roll inflation, the scalar field that drives the accelerated expansion of the
Universe is rolling down its potential at a constant rate. Within this framework, we highlight …

Once quantum corrections are taken into account, the strong coupling limit of the ξ-attractor
models (in metric gravity) might depart from the usual Starobinsky solution and move into …

A bstract We show that if the inflaton has a non-minimal coupling to gravity and the Planck
scale is dynamically generated, the results of Coleman-Weinberg inflation are confined in …

Inflationary models with a scalar field nonminimally coupled both with the Ricci scalar and
with the Gauss–Bonnet term are studied. We propose the way of generalization of …
